I am so sorry dude! I told you to go to the wrong place for the tethering hack. My Bad!
I searched and found it.Here it is :Tethering Touch with WM6.1. Step by Step instructions
need to use a reg editor to make the changes. I recommend phm regeditor. Now I know that is in the PPC Software Forum in the Commonly Requested Apps Thread.I don't understand why your gps isn't working. You might try some other gps apps and see if they can get a lock.Good Luck To You!
